Angela gained interest in fashion as a child. She said, "My father runs a fashion business in Shanghai. Even though he sells more mature clothes, I loved going to his store and trying on new outfits, and mixing and matching them. It was fun. I think that's how I developed a passion for fashion." She was first signed as a model by Style International Management when she was 14 years old.
She starred in the Japanese web drama Tweet Love Story in July 2010. The basis of the drama is audience participation via Twitter; selected viewer tweets with the hash tag #tweetlovestory would complete missing lines spoken by Yeung.
In May 2012, she signed a contract with Avex Group for activities in Japan. She has since been studying Japanese.
In 2014, she became a commercial film model of Hotel Shilla's Duty Free Shop which is an affiliated company of Samsung Group in Seoul, South Korea.
